Has anyone found any solutions to the rear brake noise? It appears to be somewhat mixed in those that have it and those that don't, but would like to know the best/quietest pads and rotors to apply during installation. For reference there will be 98% street use and maybe 2% track use on the system.

Not singling you out - just pointing out a common request we get. As far as noise goes - street pads are usually quiet and track pads are not. Well bedded pads/rotors are more quiet than those that are not and light braking is usually louder than hard braking. Race pads will 'unbed' if used cold or on the street a lot.

There is really no such thing as 'light track' You are either repeatedly braking hard (like on track) or you are not.

If you are getting noise from street pads - try bedding them a bit. Or flip them around and re-bed.

I appreciate the insight. I have not yet bought any of the components so I will look at getting the StopTech slotted rotors you recommended above and pair them with street pads. Any recommendations?

Bringing this thread back from the dead and seeking some additional input.

I currently have the Steeda 13" kit on the car, it went in before the GT500 solution was really readily available. Only 1 source for rotors and that's Steeda with their custom DBA rotor.

Since switching to Pagid pads front and rear, been having issues with the rear brakes. Moaning and calipers hanging up in reverse, grinding sounds on track with vehicle weight transfer under acceleration while turning (not during braking) and it's caused me to look into this some more.

Basically decided to go one of 2 directions.

GT500 brackets and GT500 rotors - 13.8"

Or

Go with something like the GiroDisc 11.8" rotors, but take advantage of it being a 2 piece design and significantly lighter. Giro Disc comes in under 10lbs, while a GT500 rotor pushes a little over 16lbs.

I have gotten good feedback on their durability.

Is the lighter weight and 2 piece design of the GiroDisc more advantageous than the perceived advantages of the larger rotor with more surface area of the 13.8" but a 1 piece design and heavier?

I am for now running Pagid RST-3 up front in factory 14" brembo and RS29 in the rear. Next change is a true race caliper in the front, but haven't decided on that one yet.

Any input from the experts here? Seems to me that lighter 2 piece floating rotors bring more advantages than the larger GT500 rotors with the brake bias being so heavily to the front. But that's my totally not an expert opinion from reading lots.

Before you make a wholesale change, check your rear pads; post a photo of the "centering pin" on the pad (that interfaces with the piston). I had one set of pads (albeit not Pagid) where the pins were too tall from the manufacturer and this caused the rear brakes to drag with no pedal applied. My "solution" was to file the centering pins down. Worked great. Might not be your issue but it's worth checking before you spend $$$.

Thanks for the input, definitely wanted to check everything out, and had the whole rear end gone through and rear brake assemblies checked from top to bottom when the car was getting serviced and prepped for tracking this year. Changed the rear calipers, full brake service, Everything seemed to be okay, rotors are close to end of life, but will definitely have that checked out too. Rear rotors are due for replacement soon due to wear, and I still have my factory brackets, so changing back to 11.8" rotors is just a matter of doing the work and acquiring the new rotors. I need to buy new rotors regardless, it's just which route am I going to go.

I also have some less aggressive rear pads that I can swap in to see if issues go away with those too. But I haven't been able to read of any widespread issues like I have been having with the Pagids in the rear at an RS29 like I have been using which makes me think it's something else about the set-up.

What's interesting is the major complaint is the reverse, with the brakes lightly applied, any grinding/sticking in the rear goes away, brake not applied and it can get pretty gnarly.

Just read this whole thread. A lot of good info. I do have questions. I would like to do the GT 500 rear swap on my 06. Do I only need rotors and the Gt500 calipers? Or do I need calipers as well. Also saw a brief mention of rear brake cooling. I have never seen this done. Is it possible to see som pic? Pm on that would be fine.
Thanks, Dave

If you are going the GT500 rear brake route, you only need the rotors and the brackets. The calipers are the same; although it would probably be worth looking over your calipers and seeing if they need to be rebuilt or not, assuming they are still the set that came on the car from the factory.

The GT500 calipers (like the BOSS 302 calipers) have a different part number simply because they are painted black; mechanically all the OEM rear calipers for S197 are the same (although there is some mention of a possible casting change in the link below--do your research).

Ford still offers reman calipers (Motorcraft)show they fit the Shelby but they do not come with brackets then they have GT calipers that come with the brackets that do not specify '13-14 GT500. Anything '10 and newer should clear the bigger rotor. The Ford Reman stuff is still 'cheap' at this point (Less than $200pr). I would use @pufferfish relocation brackets.

Thanks for your input. I have seen that kit on Vorshlag's page before. I have also read he entire thread on their old Mustang. I had some apprehension about the rear calipers because that car was an 11'. Probably will order a set of calipers for the GT 500 and compare. Mine are close to being toast....not the good kind of toast either.

I have an old 2012 Boss 302. I ordered & installed the individual OEM 2013/14 GT500 rear brake parts. I do remember a slight brake squeal during the first 500 - 1,000 miles but silent operation since then. (Did not pre-bed.)

Very happy with performance after several years and 10k plus miles and they look good too.
